the recess 31. The machine may be properly filled with oil through the threaded port-40 which is closed by a threaded plug 4|. i

The main-shaft I6 is driven by a belt 42 through the medium of a grooved pulley43 securedaby;

means of a set screw 44 to a horizontally dis onto the stitch-forming instrumentalities or the feed-cups, or soil the work.

. From the above description, it will be understood that there-is provided amachine-frame divided into two compartments, one of which is *oil-tight and houses actuating mechanism operating at a high rate of speed, while the other of which is opened to the atmosphere and houses 1 some of the slow speed mechanism.

i' Needle-bar mechanism Referring to Figs. 4 and 6, it will be observed posed stub-shaft 45 which is journaled 'in abushing 46. This bushing 46 is mounted in an apertiire'd mg 41 which projects inwardly'from the side wall of? the standard 2. Secured by a set screw 48 to the stub-shaft 45 is a bevelg'ear 49 which meshes with a similar gear.50 secured to'the shaft [6 by .a set screw 5|. Thus the 'belt 42 may impart rotary motion to the main-shaft l6. x

The stub-shaft 45 is lubricated by oil which runs down the outside of the main-shaft l6 and collects in a catch-pan 52 surroundin the shaft andsecuredto the lug 2| by a screw 53. This catch-pan 52 has a downturned lip portion '54 which is positioneddirectly'over a cavity 55 provided in the lug 41 for the purpose of deliveri'ng'bil-"to a radial hole 56 formed in the bushing '46. I Oil passin through the hole 56 is fed 'along'the stub-shaft by means of a spiral grodve-SfL-thereby to lubricate the shaft bearing. As may be best seen from Fig. 3, the pulley "43 and-belt 42 are enclosed by means of a housing-cap 58 secured to the standard 2 by means 'of' a screw 59 which projects through ahousing lug 66 and is threaded into the side wall of the standard 2. I

A modified form of main-shaft driving means is disclosed in Fig. 5. Here the lower portion of shaft 16 extends intoa flanged bearing-element 6| which is secured to the plate 13 by means of screws 63.- In this modification; the plate I3 is provided with a bearing-receiving aperture 64 and a gasket 65 is placed between the plate [3 and the flange of the bearing 6|. A grooved "pulley 43* is secured to the lower'portion of the shaft I 6 by means of a screw 44".

In order to prevent the oil from leaking out of thechamber ll along the shaft Hi, there is provided-in the bearing element 6| a chamber 6 which is filled with packing 61. A packing plug 68'is threaded into the lower portion of the chamber 66 for the purpose of exerting upwardpressure: upon the packing 66, thereby to provide an oil-impervious seal. j "This modified drive obviates theuse .of the hereinabove described stub-shaft 45 and its'associated gears 49 and 50. Furthermore, as best seen in Fig. 5, this construction permits the machine to be mountedupon the, usual powertable in a manner such that the driving element, including the pulley 43 and the belt 42,J are completely disposed beneath the level of the table-top T. Located in the belt compartment l 2, see Fig. l, 1s a conventional clip-belt 69 for driving the outer feed-cup l. Also located in the compartment I 2 1s a pivotally mounted supporting lever 16 for the outer feed-cup I. A lighting attachment H is disposed in the partition 10. The belt coinpartment I2 is not opened to the lubrication compartment ll, so that the oil-laden atmosphere 1n the latter compartment d'oesnot' find its way that the needle-bar mechanism comprises a needle 12 fixed in a needle-clamp 13 secured upon I a, horizontally disposed reciprocatory needle-bar l4 journaled in a bushing' 'l5 fixed in themachine-frame. The inner end portion of the'needle-bar Myhas secured thereon a collar 16 containing a vertically disposed cross-pin" which is pivotally embraced by the forked end 18 of a pitman rod 19. The end portion of the pitman rod 79 embraces a crank portion 8| of the shaft l6, As-may be seen in Fig. 6 the needle-bar 14'and;the shaft [6 have their respective longitudinal axes disposed in a single vertical plane.

From the above, it will be'obvious that rotation of the main-shaft l6 imparts to the needle-bar 74 through the connections just described, a reciprocatory motion in time with the other stitchforming instrumentalities later to be described. A thrust collar 82 'issecured upon the mainshaft It by means of a set screw 83 for the purpose of cooperating with a flange 84 of the crank M in preventing any endwise movement of the shaft l6.j-The flange 84' and'the collar 82 are each adapted'to bear against an opposite end portion of the bushing l8.

Looper mechanism Referring particularly to Figs. 3. 4 and 6, a looper -85, whichis of the threaded type, is timed so .thatit enters the 'thread-loop'presented bythe needle 12 during. the beginning of the needle-return orv withdrawal stroke, thereby car- 'ryin into the. needlethread loop a loop of thread passingthrough an eye ofjthe looper. The'1ooper'85'is" secured in a clamp 86 fastened upon the outer end of a horizontally disposed supporting shaft 81 journaled for oscillation inan angularly disposed elongated bushing 88 liked 'in the machine-frame above the level of the needle-bar l4. Clamped upon the inner end .of the looper-shaft 81 isone end of a rock-lever having at its otherend a'ball '90 and an ext'endedI'guide-pin 9|, the. ball 90 being embraced by the socketed end of a pitman 92 formed at its -other end with a split strap 93 adapted to embrace. a ball-crank 94 fastened upon the mainshaftlli. To prevent the lpitman'92 from turn- 'in g .th ere.,is;secured to one endportion thereof a "forked rnember"95" which straddles the pin .91 on the-rock-lever 89. I

'Ifhefiinction of the looper 85, as indicated lbr-ieflyabove, isv first, tos'eize the-thread-loop presented by .the needle .12, thereby enchaining the needle and looper threads, and secondly, to position that portion of thread carried by the looper and adjacent the looper-eye 96 so that thelooper-thread can be engaged by a spreader which'fpresents the looper-thread-loop to .the needle forjentrance' by. the latter. In the. ma.- chine'disclosed, these two steps are effectively carried out by a simple oscillation of the looper '85 'ab'f lli' tl'ie' longitudinal aXis' of the supportin bi human. 'M W1 arr-laser or rock-shalt 111'. Inor-derthat themovementof the looper .85 may be reduced to'a minimum, the longitudinal axis of the supporting shaft 81, see Eig.'6, is angularly arrangedat an acute angle with respect to a verticalplanepassing through the axis of the needle bai'; -It will be understoodthat the looper. point moves a single plane and that only oscillatory movements need be imparted to the lcoper. a

Referring to Fig. 4, it will he observed that the longitudinal axis of the. women-(supporting shaft 81, is disposed in a substantially horizontal plane, a aments-a;

M iscellan'eous devices :The. present machine is fitted with a lighting means adapted to direct a light to the area of the stitching point so that the operator may observe the character of the stitching and the'posi tion of the work as it passes through the machine. This lighting-means comprises a light bulb I42 carried-in a socket I43 which is mounted in an inclined cavity formed in the machine-frame wall. Current; is supplied to the lamp from a suitable source'by an insulated conductor I44 which extends through a tubular conduit I45 passing vertically through compartment H. For a more detailed description of the present lighting attachment reference may be had to my prior U. S. Patent No.-2,277-,972, March 31, 1942;

...;-When the machine illustrated is-used for certain operations, such as seaming hosiery, it is fitted with an uncurling guide I46 which uncurls and directs the edges of the fabricpreparatory to stitching. The-uncurling'guide I46 is mountediupon a bracket I41 which is secured to the machine-frameby means of a screw I48. For a more detailed description of the present type of uncurling guide reference may be had to U. S. Patent'No; 2,256,881 issued Sept. 23, 1941.

-' From the foregoing description considered in connection with the accompanying drawings, it will ire-clearthat the present machine is a markedimprovement over the prior art devices in that its actuating elements are characterized by their utmost simplicity both in construction and in arrangement. For example, by referring to Fig. 4 it 'may beseen that the driving'mechanism comprises merely 'a main-shaft IBJfrom which looper, spreader; needle and feeding elements are directly driven. No complicated ancillary mechanisms are required for:connecting these above elements with thei-maimshaft. The only connecting mechanisms herein used are. four simple pitman rods,'all of which are disposed in parallel relation with each other and at right angles-to the driving shaft I6. Thus, these actuating elements, being ofsimple design, are not only inexpensive to manufacture, but they are readily assembled within the machine-frame. Furthermore,'since the above noted four pitman rods are all conflned to operate in parallel planes at right 18 9 1! t Yel .-.ih .-.,P bb m; q P o opposite sides of and at acute angles with respect to said needle-ban'means operatively connected to said actuating shaft for driving said rockshafts, thread-handling. implements carried by said rock-shafts for-cooperation with said needle in the formation of stitches, opposed rotary v feed-cups disposed externally of said standard with their rotation axes substantially parallel to said rotary actuating shaft, and means operatively connected to said actuating shaft for driving said feed-cups. w
